2. Missing the big picture
Most students in introductory statistics courses
See statistics as disconnected topics.
Learn normal distribution for first exam…
…then forget it.
Learn confidence intervals for second exam…

3. Missing the big picture
Never see connection.
Some don’t associate 1.96 in margin of error with normal distribution.
Bigger problem: Don’t understand where confidence intervals will be in their lives.
Why do I care?

4. Problem
Need to convey to students the interconnections of statistical topics.
Need to help students develop understanding of the conceptual basis of statistics.
Need to convey to students an overall goal that motivates what topics will be covered.

5. One approach Concept maps Graphical organizer that shows topics
Presents concepts graphically
Also presents descriptive links
Links are the key.
Understand how topics interrelate.

6. Example
Why are there seasons?

8. Concept Maps for Statistics
Creating a concept map can help in identifying common threads.
Focus presentation for your students.

9. Creating a Concept Map List a few key topics
About 4, probably not more than 7.
Write them on blank paper.
Think about how they relate to course goals.

10. Creating a Concept Map Make connecting links
Draw lines that connect topics.
Write a short phrase that describes the link.

11. Creating a Concept Map Add supporting topics
Major topics that are not the most important but still important.
Again place descriptive links.

12. Creating a Concept Map Revise
Restructure your concept map to simplify appearance.
Be sure all links are listed.

13. Creating a Concept Map Identify common threads
Look for concepts that are linked to many topics.
Identify a few topics that are pivotal.

14. Your Turn
As groups you will create a concept map of introductory statistics
Based on the topics list you have from earlier.

15. Concept Maps Use it. Emphasize key concepts and course goal.
Encourage students to use it.

16. Advantages of Concept maps
Visualize concepts
Most students are visual learners.
More readily understand graphical presentation.
Connections are Explicit
Not a disconnected list of topics.

17. Conceptual Course Spend less time on minor topics.
Spend more time on common threads.
Point out the connections.
